Kees,
SU HD-carbs have diaphragms, better membranes. The membranes eventually=20
crack and break after
many years of usage. But that depends very much on the type of fuel used.
A friend of mine went on a larger tour of Scandinavia with his Jaguar XJ6 a=
=20
few years ago and
filled up with the E10+ fuel that is common there in Sweden. That was fatal=
=20
for the
carburetor membranes and also for the fuel pumps. When trying to restart=20
after the Winter
break, nothing worked on the car. Carburetters, starter (choke) carb, fuel=
=20
piumps, all membranes werebroken and shot.

SU and diaphragms????
May be meant for Stromberg carbs?
The needle in SU's is not in contact with the jet so if the carbs are set=

up properly the needles don't wear.
